In this video we try to measure the tachometer signal of a fan with an Arduino. With two resistors the signal voltage is adjusted so that it can be processed by a microcontroller. A return value of the speed (RPM) will be sent to the serial monitor.
Schematic and source code can be found as always on the blog: www.aeq-web.com/arduino-pc-lu...
